I wonder if he has access to any of those coins. 4100BTC is no joke, if he took even 5% of those supposedly hacked coins for himself then he could be in jail for a significant amount of time.
Back in 2018, he claimed that he did not have access to these funds, and that they were mostly lost in the hack. He further claims that his reimbursement plan is the result of him making some good investments over the years - but it is obvious that he could not earn 4100 BTC.
I doubt he will ever end up in prison if he doesn't by now, because he should be indicted and the authorities should know his identity.
When the Inputs.io hack happened, and CL lost most of its assets and loans, I kind of ran away from the whole bitcoin mess and settled with a portion of the accounts. But over the years, thanks to some good investments, and profitable speculative trading, I'm able to offer a reimbursement plan that I hope you're happy with. It unfortunately isn't possible to be 100% in BTC, but the average USD ROI exceeds 18x.
